Chapter 248 Defining the Scope

Chapter 249 Delimiting the scope

Forensic doctor Zhai first contacted the trace evidence laboratory to confirm the queue jumping, and then discussed the issue of wear identification with the director of his own criminal science and technology center.

The provincial department's criminal science center is of a relatively high level, with a large annual budget, and knows many scientific research institutes.

In fact, the opportunities for criminal science to truly use science are not as many as imagined.

In general, crimes such as theft are solved by internal agencies, and everyone is definitely too lazy to make it too complicated.

Contacting external agencies has certain rules and no fixed path to follow, which is really troublesome.

Only in homicide and major cases, everyone gives a little face, and then it is really easy to do it. Those reports and expenses are easy to get leaders to sign and approve.

But that said, when it really comes to the time when external resources are needed, domestic scientific research resources are actually very abundant.

Too many scientific research institutes have long reached the level of "only you can't think of it, there is nothing I can't do".

Things like trace evidence are not new in high-end research institutes in the 1970s and 1980s. As for the work of wearing snakeskin bags, it is a bit difficult for the Criminal Science Center, but it is a piece of cake for a laboratory that can do wear experiments.

The laboratories that can do wear experiments may be chemical laboratories, inorganic materials laboratories, organic materials laboratories, metal materials laboratories, mechanical laboratories, professional friction laboratories, bearing laboratories, powder metallurgy laboratories...

So, when the domestic saying that murder cases must be solved, the meaning behind it is "not moral".

Foreign famous criminal investigation agencies often recruit two or three detectives to solve cases, and the support system behind them is nothing more than two or three kittens.

Domestic theft and robbery cases are almost the same model, but when it comes to murder cases, when it is really needed, many newly-minted murderers face the domestic established scientific research system and investigation system. It is very likely that a young man with little experience will face a group of old hands.

However, this case was most likely done by an old man. It is not easy to find young people in Zifeng Mountain.

Forensic Doctor Zhai discussed everything and called Xu Taining when it was time to go to work.

Xu Taining interrupted Forensic Doctor Zhai halfway through and asked, "Where are you? I'll go over to see you."

Forensic Doctor Zhai was still a little stunned and said hurriedly, "We are in the funeral home in Qinghe City. You don't have to go there specially."

"I'll be there as soon as possible." Xu Taining didn't talk to him. He hung up the phone and scolded Forensic Doctor Zhai for being confused.

He didn't come to Zifeng Town to travel. He was busy and had thousands of people just to solve the case.

The experiment done by Jiang Yuan and others, although simple, could really solve the case.

In this case, Forensic Doctor Zhai actually thought about him...

Xu Taining just saw that Forensic Doctor Zhai was old and it was not easy to open his mouth to scold him directly.

In less than two hours, Xu Taining and his two cars drove into the funeral home in Qinghe City.

Curator Meng Deyuan came out in a hurry to greet him.

Xu Taining didn't care about him a bit, got out of the car and shook hands for five seconds, then said, "Let's go in first."

Meng Deyuan felt a little disappointed, looking at the back of Xu Taining's car, and said to his subordinates: "The temperature is lower than the soul."

"Soul egg?" The subordinate quickly gave a definition and silently sent it out in the group.

Xu Taining didn't care about so much, and he was not afraid of offending the people in Qinghe City, so he went straight to Jiang Yuan and others, listened to their explanations on the spot, and drew lines on the map.

At this time, forensic doctor Zhai explained a little embarrassedly: "We haven't finished the autopsy yet, and it may take some time to determine the source of the corpse..."

"The determination of the source of the corpse is indeed very important." Xu Taining agreed, and said: "You still have to hurry up to do the work on the source of the corpse. Let's look at the discovery of the body bag first."

Forensic doctor Zhai has been doing technology for too long, so he has formed a fixed mindset and always thinks that he has to understand the corpse.

Xu Taining doesn't have such a habit. In his experience, the window for solving a case is often so small. Just seize the opportunity and catch the criminal. He doesn't care what means are used.

For many backlog cases, most of the means are actually not feasible. He takes whatever he can find.

In this regard, Jiang Yuan has similar ideas.

It is true that he is a forensic doctor, but he has accumulated more and more means in the field of criminal science. Jiang Yuan is no longer willing to solve the case according to the model in the textbook.

Jiang Yuan explained the motorcycle experiment to Xu Taining in detail. Then, the young police officer brought by Xu Taining carried the bull forensic doctor to do another experiment.

Xu Taining did not pay much attention to the process of the experiment. Repeating the experiment was just his verification of the correct results. During this period, Xu Taining took his mobile phone and made several calls in succession.

"The car that dumped the body came from the north." With Xu Taining's urging, the trace evidence laboratory really cut in line for him.

The police officers ignored the motorcycles and the forensic cow circling in the open space, and swarmed around the map.

"If it's worn out, it's at least an hour. It also has something to do with the way you drive and the location you touch." Xu Taining said, "If they are not sure about the model and the location, it will be difficult for them to determine. With more time, they may be able to give a more accurate range."

"At least an hour, if it is confirmed, it will be a very useful conclusion." Standing next to Xu Taining was Li Liang, a senior police officer who also came from the provincial department to reinforce. Looking at the map, he said, "In one hour, Zifeng Mountain and the surrounding towns are actually ruled out first."

Xu Taining's eyes lit up: "That makes sense."

In the case of dumping corpses near Zifeng Mountain, the biggest and most suspects must be near Zifeng Town and Zifeng Mountain Coal Mine.

On the contrary, if the distance is increased, the number of suspects will be sharply reduced. At this time, considering that the person has an intersection with Zifeng Mountain Coal Mine, it will be easier to find the suspect.

Jiang Yuan thought of Wang Guoshan at the first time.

Wang Guoshan chose to dump the corpse in the reservoir, which was also a similar situation.

He neither works at the reservoir nor lives near it, but he knows something about it. Instead, he chose to drive for more than an hour to dump the body at the reservoir.

Li Liang, another senior police officer from the provincial department, also completed the logic construction at this time. He drew on the map and said, "I think we can try to check from these villages and towns 30 kilometers away from Zifeng Town, giving priority to missing women..."

Only then did forensic doctor Zhai seem to take a breath and hurriedly said, "We are also analyzing the source of the body..."

"You can look for the photos of the jewelry first." Jiang Yuan opened the photos of the jewelry he took temporarily on his mobile phone and said, "The place where these jewelry were found belongs to the same plot as the source of corpses 2 and 3. They may be the jewelry worn or owned by the deceased. I think we can ask the family members of the missing to see if anyone remembers them."

With Jiang Yuan's ability to sort garbage, he is still optimistic about the source of the jewelry.

People in different cities and with different incomes have different ways of throwing garbage.

Even though they are worthless trinkets, people in Changyang City may discard them in sets, but residents of Zifeng Town or other nearby towns will not waste them like this.

Why do concepts like "Datsu-shō-ri" appear in Tokyo and become popular in some big cities in China? In the final analysis, it is because the house area is too small. If you want to live in a more spacious place, you can only have fewer things.

In order to make the room look less empty and creepy, those villas with super large areas have to move the furniture to the middle of the room. If you also learn to "Datsu-shō-ri", you will feel that the room is like a haunted house at night.

Xu Taining and others do not need to be popularized with these simple concepts, and immediately said: "Okay, print out some photos of the trinkets and show them to the missing family members and neighbors."

Then, he urged to continue to analyze the source of the corpse.

Forensic doctor Zhai and Jiang Yuan both agreed, but they did not seem to be very confident.

Forensic anthropology is like solving an equation. It has simple solutions for some problems, such as age, race, or height, etc. As long as the bones are complete, these answers can be given, but the confidence level is a little different.

But for some problems, forensic anthropology may not necessarily find a solution. For example, the living area, the type of occupation, and even the living habits are easy to misjudge, or even fail to judge.

From Jiang Yuan's current observation, he is not very optimistic about obtaining information such as occupation or life from bones.

There is nothing to say about this. Some people work very hard or have very serious labor injuries at work. If they die at a young age, their occupation or work content can be seen from their bones.

But some people may have an easy job and like to slack off every day. Their occupational diseases are not obvious, or they may not even have occupational diseases. It is more difficult to judge their occupations through bones.

This is also the reason why Jiang Yuan recommends using jewelry to find people.

For Xu Taining, he has seen all kinds of situations. As long as there are clues, he can cheer himself up and cheer his subordinates up.

At this moment, Xu Taining's work enthusiasm has risen. He shook hands with Jiang Yuan and others and hurried back to arrange the work.

The group of people came and went quickly like a whirlwind.

At this time, the motorcycle running at a speed of 30 kilometers per hour in the open space continued to hum.

Forensic doctor Niu on the back seat hung his head and had given up struggling. He was even a little accustomed to the space on the back seat of the motorcycle. From time to time, he could adjust his posture to make himself a little more comfortable.
